I want to recommend the YouTube Music app for the Polestar 2. After years of streaming my music from my iPhone I recently subscribed to YouTube Premium and realized it comes with this music service. The app is decent and sound quality is good, but not lossless, I don’t think - not that I could hear the difference in the car. Anyway, it seems to do a good job of showing my recent music, lets me make playlists on my phone using the YouTube Music app on my iPhone, and search for anything by either typing or asking “Hey Google play…” and it defaults to YouTube Music. Anyway, not as good as Apple Music app would be but pretty good!
